This invention relates to improvements in road machines and more particularly to what known as road conditioning machines.

'The object of the invention is to provide a machine ofv this character which may be adjusted to operate as a. dirt loosener and lereler combined and as a road grader and spreader.

Another object is to so construct a machine of this class that the shoe beam and leveler or scraping blade, mayboth be adjusted to different required working positions.

Another object is to provide a road machine in which the body or frame which carries the shoe and leveling beams, may be raised or lowered and held in adjusted position and in which these beams may be adjusted individually to incline them transversely of said frame and to raise or lower one end thereof in'a quick, easy, and efficient manner.

Another object is to provide a shoe beam so constructed that the shoes may be simultaneously adjusted and held at various angles and the individual shoes removed and others substituted therefor when desired. 1 l/Vith the above and other objects in view, the invention consists of certain novel features of construction, combination andarrangement of parts as will be more fully described and claimed and shown in the drawings wherein:

Figure 1 represents a plan view of a road machine constructed in accordance with 'this in'vention; Fig. 2 is a side elevation 1; Fig. is .a vertical transverse section taken on the line 5-5 of Fig. 2.

In the embodiment illustrated, this improved road machine comprises front and rear trucks 1 and 2, the front truck 1 having a rearwardly extending V-shaped frame 3 swiveled, at its apex on the king bolt 4 in the ordinary manner. The diverging arms of this frame 3 are connected intermediately of their ends by a suitable cross bar 5forreinforcing and strengthening the V- shaped frame. Mounted on this frame 3 at the rear of the cross bar 5 is a Windlass 6 havlng a plurality of transversely extending apertures 7 arranged at different points thereon to receive removable locking pins or levers 8 any desired number of which may be employed, two being here shown.

The rear truck 2 has mounted on the axle 9 thereof, two forwardly extending arms 10 and 11 fixed at their rear ends to said axle near the ends of the axle and which are designed to support the frame of the machine hereinafter described. A cross bar 12 connects the arms 10 and 11 intermecliately of their ends, the front face of which is preferably cut away to provide suflicient space for parts mounted on said .arms in advance of said cross bar.

Mounted on the cross bar 12 is a pivoted bar or block 13 which is designed to be swung horizontally on said cross bar and has a cut out portion on its upper face as shown at 14 for a purpose to be described.

A Windlass 15 is mounted on the arms 10 and 11 in advance of the cross bar 12 and is designed for a purpose hereinafter to be described, said Windlass being provided with a plurality of apertures 16 extending transversely therethrough and positioned at different points around the periphery thereof to receive locking and actuating levers or pins 17 The bodyportion or frame of this machine is here shown rectangular in form and composed of side bars 18 and 19 connected at their opposite ends by cross bars 20 and 21 which are preferably secured to the lower faces of said side bars to provide for the positioning on their'upper faces between the side bars of the body portion of the arms 10 and 11 of the rear truck 2 and the V-shaped frame 3 of the front truck so that when in normal position, the upper faces of these members will be substan- V 6 and 15 are turned to wind up thereon tially flush with the upper faces ofthe side bars of the rectangular frame. The free ends of the V-SllflPeCl frame 3 are pivotally connected with the side bars 18 and 19 of the body portion of the machine at points the rear cross bar 20 to provide for the.

pivotal connection of said truckwith said frame and to adapt said truck to be supported by the rear cross bar 20 (see Figs. 1 and 2).

A. bar 22 preferably of metal is secured to the front edge of the front cross bar 21 and projects at its opposite ends beyond the side members 18 and 19 of the rectangular frame constituting the body portionof the machine and these projecting ends are provided in their upper edges with a plurality of longitudinally spaced notches 23 for a purpose to be described.

The front cross bar 21 of the rectangular supporting frame is flexibly connected with the Windlass 6 by means of a chain 24 or other suitable flexible element and said chain isdesigned to be wound on said windlass for adjusting the front end of the body portion of the machine relatively to the V- shaped frame 3 of the front truck to provide for the raising or lowering of said rectangular frame as will be hereinafter more fully described.

The rear cross bar 20 of the rectangular frame is similarly connected with the windlass 15 on the rear truck two chains 25 and 26 being here shown for connecting the rear truck with said frame and said chains are designed to be wound on the Windlass in a manner similar to the chain 21-.

By pivotally connecting the free or inner ends of the front and rear trucks with the rectangular frame of the'body' portion at points spaced inwardly from the rear and front cross bars of said frame, the vertical adjustment of the frame is provided for and may be controlled and regulated by the windlasses carried by the front and rear trucks. For 1I1Stfi11Ce,'Wl16I1 1t 1s desired to raise the rectangular frame, the windlasses chains which'connect them with the body portions and which when so wound, will elevate the front and'rear parts of said rectangular frame which is held in this position by passing the pins or levers 8 and 17 through the apertures in the windlasses as is shown clearly in Figs. 1 and 2, the swiveled block 13- on the rear cross bar 12 being designed to assist in elevating and holding in this position, the excavating or loosening shoes and the leveling bar hereinafter to be described, are raised out of contact wlth the surface over which the machine 1s passing which is desirable when transporting the machine from one place to another.

A keeper 27' is secured to the upper face of one of the side bars of the rectangular frame and extends about two-thirds of the length thereof, more or less, being offset from said side bara sufiicient distance to receive and guide the beam controlling bars hereinafter to be described. This keeper 2-7 is provided with a plurality of longitudinally spaced apertures 28 to receive suitable staples or U-shaped pins 29 for holding the beam controlling bars in adjusted position as will be hereinafter more fully described.

Beam controlling and supporting bars 30 and 31 extend transversely of the rectangular body portion of the machine and have one end thereof pivotally connected with the upper face of the side bar 18 as is shown clearly at 32 in Fig. 1. These bars 30 and 31 project at their free ends beyond the side bar 19 0f the rectangular frame and are provided with longitudinally extending slots 33which open downwardly through said bars and are designed to receive beam connecting links 34 and 35 for a purpose to be described. The slotted ends of these bars 30 and 31 are slidably mounted'in the keeper 27 and are adapted to be secured in adjusted position therein by the U-shaped staples 29.

Pairs of spaced uprights36 and 37 are carried by each of the bars 30 and 31 and each pair of said uprights is spaced longitudi nally from the other pair, said uprights being here shown secured to the opposite side edges of their respective bars and designed to support beam controlling levers 38 and 397 said levers being fulcrumed intermediately of their ends between the pair of uprights .between the legs of the clips 46.

and which are designed to hold said levers in adjusted position. The ends of the le vers 38 and 39 which project beyond the pairs of standards 37 are connected with the links 34 and 35 which pass through the slots in the beam controlling bars 30 and 31 and through these links, said levers are de signed to elevate or lower the shoe beam and leveling blade with which said links are connected.

A shoe carrying beam 45 extends transversely below the .rectangular frame and projects at its opposite ends any suitable or desired distance beyond the side members of said frame and one end of said bar is connected with the pivoted end of the beam controlling bar 30 by any suitable means, eye-bolts 42 and 43 being here shown for connecting said bars at this end. The other end of this bar 45 is connected with one of the links 35, said link being here shown connected with said bar by an eye-bolt 44, (see Fig. 3). w

Arranged at the rear of the shoe carrying beam is a leveling or scraping beam 50 which is connected with the bar 31 in a manner similar to the shoe carrying beam, one of the links 34 being employed for connecting one end thereof and the other end adjacent the pivoted end of the bar 31 being connected by two interengaging eyebolts 42 and 43.

Mounted on the shoe beam 45 are a plurality of U-shaped metal clips 46 between the arms of which said bar is mounted, one of said arms being disposed on the upper face of said bar and the other on the lower face thereof and being connected with the bar by means of suitable pivot devices 47 here shown in the form of bolts. The free ends of the arms of these clips project some distance beyond the bar 45 and have pivotally connected therewith, a locking bar 48 which is also formed of metal and is designed for simultaneously operating the clips 46 which carry the shoes 60. The'cross bars of the U-shaped clips 46 are arranged in front of the beam 45 and have rigidly secured thereto auxiliary shoe carrying clips 49 which are here shown U-shaped with the openings between the legs thereof disposed in a plane at right angles to the openings clips 49 are cast or formed in any other suitable mannerand of metal sufiiciently rigid to support the shoes. The legs or arms of these clips 49 are positioned to receive between them the shanks 61 of the shoes 60. These shanks 61 are provided with a plurality of longitudinally spaced apertures which are designed to register with similar apertures formed in the. arms of the clip.

members 49 and through which are passed fastening pins or bolts and Q3 which rigidly secure the shoes in operative posi- These tion in said clips 49, (see Fig. 4). These clips 49 are shown riveted to the clips. 46 but it is obvious that they may be cast integral therewith.

From the above description, it will be obvious that the shoe carrying clips 46 are pivoted individually on the beam 45 and that their rearwardly pro ecting ends are pivotally connected with the adjusting bar 48 and they are held in adjusted position by means of a link 64 which is pivotally connected atone end with the beam 45 about midway the length thereof and has a down turned end 65 which is adapted to. be engaged with one of a series of apertures 66 formed in a lateral extension 67 formed on one. end of the bar 48. As shown, this link 64 is provided with an operating handle 68 for changing the position thereof from one ofsaid apertures to another according to the position in which it is desired to lock the shoes 60. By shifting this bar 48 the shoes may be turned in a plane oblique to the beam 45 or in planes at right angles thereto as may be desired. Means for securing the shoe beam 45 in position from wabbling are here shown in the form of chains 69 connected with the opposite ends of said beam and which are designed to be inserted in the notches formed at the opposite ends of the bar 22, see 1, said chains being held in said notches by the engagement of the links therewith or in any suitable manner.

The leveling blade 50 which depends from 100 the'bar 31 may be of any suitable or desired construction and is here shown wedgeshape in cross section with the thin end or knife edge thereof positioned to engage the surface of the road over which the machine 105 is drawn for leveling the earth dug up or loosened by the shoe 60 and which is designed for pushing or scraping the dirt loosened by the shoes into the low places of the road and thus forming a level road'bed.

If desired. however this blade ma the em- 1 l ployed as a scraping blade for scraping off the surface of the road and which also serves to distribute evenly the dirt loosened by the shoes.

This leveling blade is also held in operative position against wabbling by means of suitable chains 51 and links 52 connected therewith, said chains being adapted to be engaged with one of the notches 23 in the frame in planes at right angles thereto or they may be positioned obliquely relatively to said frame as shown in Fig. 1 and when they have been positioned as desired, they are locked into this position by means of the U- shaped pins 29 which are passed through suitable apertures 28 in the keeper 27 and consequently, lock the free ends of the beam controlling bars 30 and 31 in adjusted position. When these bars have been so adjusted, the pins are again inserted in the desired apertures in the uprights 37 for positioning the shoe beam and leveling blade either in horizontal position or with one end thereof inclined upwardly as may be desired and when so positioned, the securing chains 51 and 69 of said beam and blade are engaged with the notches in the cross bar 22 and the machine is then ready for operation. After the parts of the machine have been so disposed, the rectangular frame or body portion of the machine may be dropped to bring the shoes and blade into operative engagement with the surface on which it is designed to operate by unwinding the chains which connect the front and rear ends of the frame with the windlasses on the front and rear trucks as heretofore described and when the machine is drawn over the road bed the shoes 60 will dig or loosen the earth and the leveling blade passing behind them will drag or push the earth so loosened into the uneven spaces and thus level the road bed.

The lower faces of the arms of the V- shaped member 3 of the front truck are preferably cut out to form shoulders 3 which are designed to engage the rear faces of the cross bar 21 to assist in holding the truck in operative position and prevent its wabbling.

This machine may be made of any desired size preferably from five to forty feet long and from three to fourteen feet wide, as may be found desirable in connection with the work on which it is to be used.

I claim as my invention:

1. In a road machine, a shoe beam, a plurality of longitudinally spaced U-shaped clips straddling said beam with the arms thereof pivotally connected with said beam and having their free ends projecting beyond the rear face of the beam, shoes mounted on the cross bars of said clips, and an adjusting bar connected with the projecting ends of said clip arms.
